Two EXPOSE equipments have been developed: EXPOSE-E and EXPOSE-R. EXPOSE-E is installed on the European module Columbus, and more particularly, on EuteF platform, while EXPOSE-R is installed on the Russian module Zevzda.
Each of these EXPOSE facilities includes several simultaneous experiments. The different experiments consist in exposing solid molecules, gas mixtures or biological samples to the radiations in space, to space vacuum and to temperature fluctuations.

EXPOSE-E experiments are:

Process, study of solar UV effects on amino acids and other organic compounds placed in terrestrial orbit.
Adapt, study of radiations effect on micro-organisms in analogues to meteoritic matter.
Protect, study of spores resistance to space conditions, and their ability to recover from the damages done by such an exposition.
Life, study of radiations effect on lichens, mushrooms and symbiotes.
Seeds, exposition of seeds to space conditions and study of their ability to resist to radiations.
Dosis, Dobis & R3D, radiations and radiance sensors.

EXPOSE-R experiments are:

Amino, study of solar UV effects on amino acids and other organic compounds placed in terrestrial orbit.
Endo, study of radiations effect on endolithic micro-organisms (living under rock surface).
Osmo, study of the exposition of osmophilic micro-organismes (living in medium highly concentrated in sugar) to space environment.
Spores, study of spores placed inside artificial meteorites.
Photo, study of solar radiation effect on genetic material of spores.
Subtil, study of mutagen effect of space environment on bactery spores (Bacillus subtilis).
Pur, study of space environment effect on T7 phage, its DNA and of polycristalline uracil.
Organic, study of the evolution of organic matter placed in space.
IMBP, exposition of terrestrial organisms in a matent state.

CNES participation to EXPOSE consists particularly in supporting the development of PROCESS and AMINO experiments. CNES has also financialy supported SEEDS experiment.
